Thanks for clarifying. It's a shame the one big new feature of the new firmware is also the bringer of an eqial measure of issues...personally I can't see how books on shelves should have any relevance to the home page unless it's being scraped to generate recommendations..
Kobo must be motivated to fix it as these days I never go back to the home page relying on the search tool instead, so I'm missing out on viewing all that lovely advertising content they foist on me.
